What up every one? Right now im 21 5'11" 220. I have a metabolism that wont stop ive been traing for 4 years now and bulking for close to the last year. My lasf bf was like 10%. I like my been lean year round no matter what i eat but my quads are really falling behind. Up top im perfect in my own eyes my chest, arms back are full and pretty solid but moving on down my legs are horrible. If my legs would catch up i swear id be close to 235. Any advice. I was once suggested to add cardio such as bike back to my routine(sadly i havent done cardio in who knows how long). my typically leg routine includes squats, leg press, extensions, ham curls, stiff leg deadlifts. BUt i allways mix it up and never do the same leg workout the next week. Also since my legs lag so bad ive lost alot of the intensity i usally carry into my leg day. all advice is most appreciated.
